Leipzig Blue-Green – Blue-Green Quarter Development in Leipzig

Process control of blue‑green infrastructures in Leipzig

Leipzig is a growing metropolis; the development of further residential areas in the city center is therefore an important goal of urban development. However, structural redensification and the consequences of climate change (heat, heavy rainfall) place an enormous burden on the water and energy infrastructure. The city's parties involved are thus confronted with new planning and legal issues.

The BMBF‑funded joint project "Leipzig Blue‑Green – Blue‑Green Quarter Development in Leipzig" is intended to show, using the example of the large‑scale project "Eutritzscher Freiladebahnhof" (Eutritzsch Free Loading Station), how a runoff‑free and resource‑efficient urban quarter can be designed. Blue stands for water, green for plants as an element of urban infrastructure. The aim is to develop new, transferable blue‑green technologies and planning tools as well as a sensor‑based, robust process control.

Fraunhofer IGB is investigating how the combination of blue‑green technologies can be controlled equally robustly and efficiently and how the operation and maintenance of the system architecture can be ensured sustainably. In this context, the IGB's experience in process automation and handling of measurement data can be transferred to the urban district level. In a first step, elements such as green roofs will be automated on the campus of the Helmholtz Center for Environmental Research Leipzig, e.g. by controlling the runoff based on weather forecasts. The results are then transferred to the planned quarter.
